WHAT IS A CACHE?

in #technology7 years ago

You are always seeing the word "CLEAR CACHE" and you just click & you don't know what it is, well it's time you knew;
Cache is an important principle of computer system & smartphone platforms. and here's how it works. Information is normally kept in some storage system (such as main memory).As it is used ,it is copied into a faster storage system ,the cache on a temporary basis, when we need a particular piece of information, we first check whether it Is in the cache. If it is, we use the information directly from the cache. If it is not, weth1YIAMDW2.jpg use the information from the source ,putting a copy in the CACHE under the assumption that we would need it again soon. CACHE maximize Speed and Performance, when you use your browser to look at a website for the first time, it stores information from the site in temporary files in its cache. When you go to the site again, your browser will load it from the cache copy rather than downloading it all over again from the Internet. This process aims to speed up your overall browsing experience. Website pages can contain many different elements -- if you load them up from the stored cache version, you'll have quicker load times. Caching files can have some disadvantages, however, and it sometimes makes sense to clear the cache.

If you spend a lot of time online or have been visiting websites for a long period, then you may build up a sizeable cache. This may affect the speed and performance of your computer as you surf online, especially if you are low on hard drive capacity anyway. Clearing the cache frees up some space and may just speed things back up again. Keep in mind that this may not make a huge difference -- you're more likely to see a slight change.
